Retrospective 700 patients with autoimmune rheumatic disease in Qatar, showing lower risk of COVID-19 with HCQ use, without statistical significance. For patients having close contact with COVID-19 cases, there was a statistically significant association with HCQ use and lower risk of COVID-19 in unadjusted results.
risk of case, 36.8% lower, RR 0.63, p = 0.17, treatment 26 of 314 (8.3%), control 49 of 386 (12.7%), NNT 23, adjusted per study, odds ratio converted to relative risk, multivariable.
risk of case, 52.0% lower, RR 0.48, p < 0.001, treatment 16 of 46 (34.8%), control 29 of 40 (72.5%), NNT 2.7, patients with close contact to cases, close contact.
